This used to be a thing back in the day I believe. I wonder if the NBA brought it back, if it might help with load management. So, if a player is going to sit out, they have to go on the injury list, which means a minimum of a certain number of games missed. I think 3 games seems reasonable. So if you are going to sit out a game you could otherwise play, you have to miss 2 other games. It wouldn't end load management, but would make it more strategic. I'd also give each player 2 or 3 exceptions. So a guy comes down a fever, you can use the exception and he can miss 1 game without being on the injury list. The league would be responsible for determining if a player is a legitimate DNP Coaches decision so teams don't get into trouble with bench players and what not and so teams don't try to usurp the rule by having a player dress who then just isn't played. You can still rest and load manage, but it comes at the expense of 3 straight games missed.
